Just a suggestion. The Decision tool at the moment will have 2 grey lines coming out of it, (1 for the true output and 1 for the false output). This is fine for simple workflows, however as the workflows get more and more complex, there are instances where outputs from decisions will overlap each other and head toward the same assign/workflow/process etc. Is is possible that when clicked on, the decision tool itself and the output lines are highlighted as well so that somebody using the program would have an easier time following the process flow with having to open up the tools to have a look at the outputs?
